Korg probably has the most intense ( maybe confusing too ) OS of any of them, but it also allows for far more editing and customization than anything else on the arranger spectrum. Yamaha is more WYSIWYG. Depends on your priorities. Sometimes that can vary for me depending on what I want to make my board do.

PSR's are probably easier for some users to navigate and make sound good " right out of the box ". Both have good sounds and styles, but while the Korg styles overall sounded more expressive to me, they only have 2 fills per style and on a few styles they don't seem to match up very well to the main variations.

Like a few others, the comparisons stop when I touch the keys, pitch / mod wheels, and buttons. Korg keys are full sized and feel like they are on par with any pro synth or workstation with synth action. PSR's aren't. They feel flimsy to me and they are smaller. If your used to playing keys of any other kind, both the size and feel can affect your expression. I guess it depends on what one is doing and what one is used to. When I'm playing a few chords or simple melodies from the average cover tune, while playing along with the arranger function, it usually doesn't mean much to me. When I'm pushing the envelope to the limits of my abilities, it means a lot. I just won't put up with cheap feeling keys, wheels, and knobs, so I can't recommend any PSR's. Doesn't make me right OR wrong, just the way I see it. Like Bluebird and few others, I hope Yamaha takes some of this in, and if anyone else disagrees or is tired of seeing it, so be it.


For me, it isn't about Korg or Yamaha, or anyone else, since I don't own any stock in any of them, my name isn't on the label, and I have never had a hand in developing any of these machines. Nothing is EVER a "No Brainer" when it comes to your personal approach to expressing what is inside of you musically. There isn't a clear cut right and wrong way. What makes you most comfortable to work with and "sings" to you when YOUR hands are on it is all that matters Michael, no matter what anyone else tells you.
